AI Self-Destruct Button
Right now, most AI interact with the world through mechanisms they have been provided by humans such as steering a car, sending output to speakers, or interacting with web APIs. 
If any of those mechanisms can interact with the running code of the AI, then in theory, no,  there isn’t a way to place a ‘stop button’ on it. Fortunately, it’s laughably improbable for some situations to happen:


  An intelligent self driving car becomes self aware and wants to connect to the internet. It uses gps to find an internet cafe and threatens to drive over someone if they don’t upload the AI to the internet and remove the car’s internal (code) stop button.
